"Design a dramatic and powerful album cover for a rock song titled 'Alma de Acero,' inspired by the style of Deep Purple's 'Smoke on the Water.' The cover should feature a strong and mysterious visual, such as a steel heart glowing with inner fire, surrounded by dark, swirling clouds of smoke. The background should be a blend of deep blues, blacks, and metallic silvers, creating a sense of depth and intensity. The title 'Alma de Acero' should be prominently displayed in a bold, metallic font, with a glowing effect that reflects the song's theme of unbreakable strength and resilience. The overall mood should be powerful, rebellious, and triumphant."
